This private website lists all European bird research projects with colour-rings (August 2010: 1996 colour-ring projects on 355 bird species). Colour-ringing of birds has a huge advantage against classic ringing with just one metal ring. You can read the colour-rings in field with binoculars, thus you can obtain much data without disturbing or harming the bird. On this website you can find all European colour-ring projects and their coordinators. Observers of colour-ringed birds can contact the coordinators and get information about the origin of these birds. [Editorial staff vifabio]
